Answer:

All rocks have same thermal conductivity.

Explanation:

Rocks are heated with the sunlight exposure. Different types of rocks have different thermal conductivity. The heat energy of the rocks is measure in Joules. The size and thermal conductivity of the rocks is important property which determines their heating capacity.

If a patient requires 30g/day of some medication and it comes in 500 mg tablets , how many tablets does this patient need in one
Anna11 [10]
Since 1000 mg=1g 
            500mg=?
500/1000*1g=0.5g
       Since we know that 500mg is 0.5g then divide 30g by 0.5g
30/0.5=60
Therefore the patients needs to take 60 tablets a day.

Consider the following equilibrium between N2O4 and NO2.[Heat is added to a brown 2 NO2 gas to yield a colorless N2O4 gas]Which
LekaFEV [45]

Answer:

a.Low temperature

Explanation

Equation of reaction:

2NO2 <==> N2O4(g) ∆H = +ve

To cause the reaction to become darker brown means to produce more of NO2 gas. That is backward reaction.

Since the reaction is endothermic, decrease in temperature will shift the equilibrium position to the left thereby favouring backward reaction. This is in line with Me Chatelier's principle.

High pressure will rather favour forward reaction (it is not the right option).
